Classes known to DWR:

[dengyang163]

我刚学到ajax没几天 用Ajax时（也用spring了）就出现Classes known to DWR:

问题就是 我导入dwr.jar 配置好web.xml和dwr.xml
然后部署项目 在ie中输入http://localhost:8080/epet/dwr/index.html

页面中只显示Classes known to DWR: 什么也没有了 更没有公布的方法

好心的前辈们，教教虚心学习的后背吧，谢谢啦，帮帮忙

dwr.xml文件就放在WEB-INF下 内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://getahead.org/dwr/dwr20.dtd">

<dwr>
<allow>
<create creator="spring" javascript="JUserCheck">
<param name="beanName" value="petInfoBizImpl" />
<param name="location" value="classpath:di.xml" />
</create>
</allow>

</dwr>

web.xml 内容如下：
<?xml version="1.0" encoding="UTF-8"?>

dwr的一个链接
http://hi.baidu.com/29163077/blog/item/4409d910abc724ffc2ce793f.html

楼主我没用过dwr，你参考下，如果有用就好。没用就当帮顶。

[dengyang163]

发不的类写进去了啊 value值对应spring配置文件中的bean id 都对着里啊 可郁闷 谢谢你们 啊

[dengyang163]

上面的师哥发的连接很有用， 小弟在此谢过了 但问题仍是没有解决 咳

[zhuwen9]

dwr.xml文件 有把你要发布的类写进去没?

[杰森-李]

我也遇到了同样的问题，还请各位多多指教

[java_亮]

默认的无参构造有吗

[CloudX2019]

是要用com.aptech.jb.epet.biz.impl.PetInfoBizImpl这个类里面的方法么？你是怎么注入的?貌似是用的set方法

Spring 很久没有用了，帮不了
<create creator="spring" javascript="JUserCheck">
<param name="beanName" value="petInfoBizImpl" />
<param name="location" value="classpath:di.xml" /></create>
个人感觉这里有问题

[脚本小子]

仔细看看你控制台报的错误~~
